Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody. Illumina sequencing libraries were prepared from the ChIP and Input DNAs by the standard consecutive enzymatic steps of end-polishing, dA-addition, and adaptor ligation. After a final PCR amplification step, the resulting DNA libraries were quantified and sequenced on a NexSeq 500 (100 bp, single end reads).
